目的:观察妊娠期糖尿病孕妇胎儿脐动脉、肾动脉血流动力学指标,并且分析这些指标与预后的相关性。方法:选择120例妊娠期糖尿病孕妇为观察组,100例正常妊娠孕妇为对照组,采用彩色多普勒超声检测两组胎儿脐动脉、肾动脉血流动力学指标,并且分析上述指标与预后的相关性。结果:观察组脐动脉、肾动脉收缩期最大血流速度与舒张末期血流速度的比值(S/D)及阻力指数(RI)均高于对照组;脐动脉、肾动脉血流异常者胎儿生长受限、胎儿窘迫、新生儿窒息发生率高于脐动脉、肾动脉血流正常者,差异有统计学意义(P<0.05)。结论:彩色多普勒超声检测脐动脉、肾动脉血流动力学指标能够较好地预测妊娠期糖尿病孕妇胎儿的预后,及早发现胎儿生长受限、胎儿窘迫及新生儿窒息。
Objective: To observe the fetal umbilical artery and renal artery hemodynamics in pregnant women with gestational diabetes mellitus, and to analyze the correlation between these indexes and prognosis. Methods: 120 pregnant women with gestational diabetes mellitus were selected as the observation group and 100 normal pregnant women as the control group. The umbilical artery and renal artery hemodynamics were detected by color Doppler sonography. The indexes and prognosis Correlation. Results: The ratio of S / D and RI in systolic phase of umbilical artery and renal artery in observation group were significantly higher than those in control group. Umbilical artery, abnormal renal flow in fetus Growth restriction, fetal distress, the incidence of neonatal asphyxia than umbilical artery, renal artery blood flow was normal, the difference was statistically significant (P <0.05). Conclusion: The color Doppler ultrasound detection of umbilical artery and renal artery hemodynamics can predict the prognosis of fetus in gestational diabetes mellitus well, find fetal growth restriction, fetal distress and neonatal asphyxia early.
